Description

[Detailed description of the invention] (Field of industrial application) The present invention is designed so that after a binding band is inserted into a hole provided in an object to be bound such as documents, the upper surface of the binding band is inserted so as to sandwich the object to be bound. The present invention relates to a file binding device that fixes the leading end of a binding band to a presser base plate placed on a holding base plate placed on a holding board.

(Prior art) Conventionally, for example, a guide rail has sliding grooves on both the left and right sides and a through hole through which the binding tape is passed, and pressers that can slide freely through the sliding grooves are attached at both ends of the guide rail. A file binding device that has a presser, a central finger holder, and a connector and is connected so that it can be bent only from the front to the back is disclosed in Japanese Utility Model Application Publication No. 51-49125, and a similar binding device. The type of fitting in which the above-mentioned connector is directly attached in a bendable manner was developed in 1983.
-20379 and the like, each of which is publicly known.

(Problem to be solved by the invention) However, among these structures, in the former case, it is difficult to release the binding again after pressing down the central finger hook and completing the binding of the binding tape by the presser. This method makes it difficult for the user to directly pick up the finger hook, which remains in close contact with the top surface of the guide rail, with the fingertips and forcibly pull it upwards during the above-mentioned binding process, and also to avoid applying force to the fingertips. In order to release the binding even in the latter case,
In order to peel off the connector, which is also tightly attached to the top surface of the guide rail, from the same surface, it is necessary to perform the same troublesome and forceful lifting operation with the fingertips as described above for the joint between the two. It is something that
Both had technical problems that needed to be solved, such as poor workability during unbinding.

(Means for Solving the Problems) The present invention consists of a pair of flexible binding bands that protrude above the inner surface of the cover body and are inserted into holes provided in the documents to be bound, and A press base plate has a through hole near both ends through which the tip of the binding band protruding from the hole of the loaded documents is inserted, and has a bending/extending leg part in the center and presser pieces at both ends. Then, the presser piece is slidably attached to the presser base plate, and when the bending/extending leg portion is bent, the presser piece moves to a position inside the through hole in the center direction of the presser base plate to release the binding band. and a holder that bends and fixes the binding band by moving the presser piece to an outer position from the through hole in the end direction of the presser board when the bending and extending leg is in an extended state. A hinge part is provided at the boundary between the center part and the pressing pieces at both ends, and a lever part is provided in the bending/extending leg part on one side and protruding beyond the hinge part in the center toward the bending/extending leg part on the opposite side. is,
An attempt is made to solve this problem by providing a file binding device characterized in that the bending and extending leg on the opposite side is provided with a notch that is longer and wider than the length and width of the lever part. It is something to do.

The holder 8 is attached by slidably fitting the presser pieces 10 at both ends onto the rails 6 of the presser board 3. To explain the bending/extending legs 9 of the holder 8 in more detail, hinges 11 are provided at the boundaries between the center and the presser pieces 10 at both ends, and the bending/extending legs 9 on one side are provided with hinges 11 at the center. A lever part 12 is provided that extends beyond the bending/extending leg part 9 on the opposite side, and a notch part 13 is provided in the bending/extending leg part 9 on the opposite side, which is longer and wider than the length and width of the lever part 12.
Furthermore, ribs 14 are provided on the lower surface sides of both side edges of each of the bending/extending legs 9 on both sides, and the ribs 14 are shaped so that they do not come into contact with each other when bent.
4 is provided with an elastically deformable locking protrusion 15 on its inner surface.

FIG. 1 shows the released state of the binding band 1, in which the bending/extending legs 9 of the holder 8 are bent in an inverted V shape and floating, and the presser pieces 10 at both ends of the holder 8 are pressed. It moves toward the center of the substrate 3 and is located inside the through hole 5. In this state, the binding band 1 is removed from the through hole 5 of the presser board 3 to insert and remove the document. FIG. 2 shows the fixed state of the binding band 1. By pressing the center part of the bending/extending leg part 9 downward from the state shown in FIG. The presser piece portions 10 move outward to positions that cover the upper surfaces of the through holes 5, respectively.
